I hope I am posting this in the right place! My entry is a couple of craft supply caddies made from juice boxes, Shout Color Catcher boxes, and the metal handles from Chinese food takeout boxes. Here are the containers:

Here are the caddies empty:

And here they are loaded up with markers, pencils, rulers and paint brushes:

The juice box caddy is made of 6 boxes, with 2 rows of 3 boxes joined back to back with strong doublestick tape. The metal takeout box handle fit perfectly into the straw holes in the juice boxes. The other caddy is made of 2 Color Catcher boxes taped back to back. I removed the top flap of the box and added a bit of electrical tape along the top edge for reinforcement and poked holes for the handles. These things look flimsy but are actually fairly durable. They're great for carrying and storing craft supplies. You could also use them for carrying your dining utensils and napkins outdoors.

Thank you! There is no decoupage or decoration of any sort, just the packaging. The adhesive was the only part that wasn't recycled. Of course, there's no reason you couldn't make it prettier by decorating it, but I've been on a big reuse kick for a while and I don't mind if my projects look obviously recycled. I hope that, if people can plainly see how I've reused an object, it will get them thinking about doing something similar.
